Dripless pouring spout



Patented July 20, 1954 DRIPLESS POURING SPOUT Dorace E. Motz, Winchester, Idaho Application January 11, 1952, Serial No. 265,979

2 Claims.

This invention relates generally to a dripless cap, and more particularly to a dripless cap having a pouring spout, said cap being adapted for use with a vacuum bottle.

It is well known that the conventional Vacuum bottle has a relatively small pouring opening with respect to the diameter of the upper end so that it is diflicult to pour liquids from the vacuum bottle when it is filled to the top. It is obvious that the pouring of liquids from a vacuum bottle would be much less messy, with less liquid being spilled if the vacuum bottle were provided with a suitable pouring spout.

The primary object of this invention is to provide a dripless cap for a vacuum bottle in the form of a pouring spout for attachment to the upper end of a vacuum bottle.

Another object of this invention is to form an improved dripless cap having a pouring spout which may be secured to the upper end of a vacuum bottle, and conveniently removed for washing both the cap and the upper end of the vacuum bottle.

Another object of this invention is to provide a dripless cap for a vacuum bottle which is made of a slightly resilient material so that it may be compressibly engaged over the upper end of the vacuum bottle.

A further object of this invention is to provide a dripless cap for vacuum bottles with said cap having a pouring spout, and said cap being of such configuration that it may be installed on the upper end of a vacuum bottle and within the conventional cap for a vacuum bottle.

With these objects definitely in view, this invention resides in certain novel features of construction, combination and arrangement of elements and portions as will be hereinafter described in detail in the specification, particularly pointed out in the appended claims, and illustrated in the accompanying drawings which form a material part of this application, and in which:

Figure 1 is a partial central transverse vertical sectional view showing the dripless cap, which forms the subject of this invention, secured to the upper end of a conventional vacuum bottle;

Figure 2 is a horizontal sectional view taken substantially upon the plane indicated by the section line 2-2 of Figure 1 and showing the construction of the spout on the dripless cap; and

Figure 3 is a front elevational view of the dripless cap, which forms the subject of this inven tion.

Similar characters of reference designate similar or identical elements and portions throughout the specification and throughout the different views of the drawings.

Referring now to the drawings in detail, the novel dripless cap, which forms the subject of this invention, is illustrated in Figure 1 as being attached to a conventional vacuum bottle which will be referred to in general by the reference numeral 0.

The vacuum bottle Ill includes an outer metal casing 12 which is formed at its upper end with a reduced shoulder l4 which is bent to form a plurality of external threads IS. The outer metal casing I2 is further reduced to form a top shoulder I8 which is in firm engagement with the neck of an inner casing 22.

The inner casing 22 is in the form of a double wall glass container having an outer wall 24 and an inner wall 26 in spaced relation to the outer wall 24. Within the inner wall 26 is a liquid receiving space 28. In the vicinity'of the neck 2! the inner wall 26 is tubular to form a liquid receiving and discharge opening 30. The outer wall 24 also has a tubular portion 32 in the area of the neck 20, the tubular portion 32 of the outer wall 24 being joined to the tubular portion 30 of the inner wall 26 at their upper ends. The tubular portion 32 of the outer wall 24 is in firm engagement with the upper end of the metal casing 12.

In order to close the tubular liquid receiving and discharge opening 30, the vacuum bottle I0 is provided with a cork 34 tightly engaged within the tubular opening 30. The vacuum bottle I!) is provided with a cup-shaped cap 36. The cup-shaped cap 36 has a top wall 38 and a cylindrical side wall 46. The cylindrical side wall 40 is bent to form a plurality of threads 42 which are in engagement with the threads It on the shoulder 14 of the outer metal casing l2.

The dripless cap, which forms the subject of this invention, is referred to generally by the reference numeral 44. The cap 44 has a substantially circular body portion 46 and a curved pouring spout 48. The circular body portion 46 has an enlarged bore in its lower side, the bore 5!] engaging over the shoulder 18 of the metal outer casing [22. The body portion 46 is also provided with an intermediate concentric smaller bore 52 which is in engagement with the tubular portion 32 of the outer wall 24 of the inner casing 22 and encloses the upper end of the inner casing 22. The body portion 46 is also provided with a concentric bore 54 through its upper side, the

" bore 54 being in alignment with the tubular opensurface of thel body portion 46 'and the spouti48, i that any fiuid left in the spout 46 duringthe pouring process will return to the fluid receiving compartment 28 through the tubular opening of the vacuum bottle Hi.

In order that the cap 44 may be easily removed from the vacuum bottle Ill for washing, tand at-i the same time be firmly secured thereon, it is made of a resilient material suchas rubber, ora suitable plastic.

Minor modification of the cap, varying in minor details. fromthe embodiment ofitheicap illustrated and described hereini'may-be. resorted to :withduti departure from the spirit and... scope oflthe" in' vention, has defined in the appended claims.

Having described the invention, What is claimed as new is:-

1."A'removable pouringpspout for a'vacuum bottle" comprising a circular body. portion and a pouring spout integral with said body portion, said body portion having an internal configuration to fit tightly over the top of said vacuum bottle, said body portion having a large lower bore for engagement over a top shoulder of the outer case of the vacuum bottle, an intermediate smaller bore for engagement over the top of the inner casing of the vacuum bottle, and a still smaller bore at the upper side of said body portion for engagement with a sealing cork.

2. A removable pouring spout for a vacuum bottle. comprising a circularcbody'iportion and a pouring spout integral with said- 'body' portion, said body portion having an internal configuration to fit tightly over the top of said vacuum bottle, -said. body portion having a large lower bore for engagement over a top shoulder of the outericase ofnthe vacuum bottle, an intermediate smaller bore for engagement over the top of the inner casing of thevacuum bottle, and a still smaller-bore at the upper side of said body portion for engagement with a sealing cork, said bodyportion being formed of a slightly resilient materialitwhereby, said bodyi, portion may be jammed "over the upper end otthe vacuum v bottle;
